The Monroe Horizontal Plate Clarifier is one of the most versatile clarifiers available on the market. Because the unique Monroe parallel separator plate design effectively separates both settleable solids and floating materials, the Horizontal Clarifier can be used in place of a circular clarifier for nearly any application. This allows for significant cost savings and reduced space requirements versus traditional clarifiers. These advantages have made the Horizontal Clarifier the best-selling clarifier offered by Monroe over the past 40+ years.

Horizontal Inclined Plate Clarifier Capabilities

Oil Recovery — Separated oils, process fluids and other floatable materials are guided to an accumulation area for easy removal and reclamation. An adjustable pipe skimmer or a Monroe Oil Skimmer can be included to remove these elements.

Heavy Solids Removal — Where the dirt load is heavy, a screw auger or drag conveyor may be included (see below) to provide continuous removal of settled solids from the bottom of the clarifier.

Chemical Treatment — The Monroe Parallel Plate Horizontal Clarifier can include a pre-treatment process as an integral part of the basic clarifier. This aids in the separation of dissolved solids, very fine particles and emulsified oils that tend to remain suspended in water or process fluids. A chemical treatment tank and/or flocculation chamber can be added to allow pH control and mixing of emulsion breakers and coagulants into the influent before the laminar flow process.

Monroe Parallel Plate Horizontal Clarifiers vs. Typical Separators

In the Monroe Parallel Plate Horizontal Clarifier separated particles are required to move only a few inches before reaching an uninterrupted and protected free fall or rise to collection areas. Efficiency is increased and build-up of collected particles is prevented.

In typical separators long laminar sections require particles to travel as much as 10 feet before free fall or rise to collection areas, often causing clogging and re-entrainment with other fluid flow currents, reducing separation efficiency.

Laminar Flow Principle for Inclined Plate Clarifiers

The unique design of the Monroe Parallel Plate Horizontal Clarifier creates laminar flow conditions and allows gravitational forces to separate the lighter and heavier elements from the fluid.
